The Ingersoll Rand 22055909 tee has a 1/4" connection on the right side that attaches to the solenoid valve. The larger poly line connection comes off the left side with tubing that typicallly routes back below the separator element. The smaller bottom line connects its tubing back to the second solenoid valve.
This tee was used on a wide range of the Ingersoll Rand rotary screw air compressors, including the UP6-20, UP6-25, UP6-30, UP6-40 and UP6-50. This was also used on certain versions of their RS series. Please contact us with your serial number for confirmation this will work with your rotary screw air compressor.
